Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a rotary powder discharging combined bottle cap. Background Art

[0002] In the fields of food and health products, premixed liquid forms are often used, such as beverages and oral liquids. However, the biggest problem with food and health products in premixed liquid form is that they are easily affected by external factors and lose their activity and deteriorate, such as light, heat, oxygen, ultraviolet rays, etc. For this reason, some preservatives, fresh-keeping agents, and stabilizers need to be added. Even so, the shelf life of premixed liquids is still shorter than that of solids. In addition, during the storage of liquid preparations, the taste changes due to time and environment, which also restricts the development of various foods, such as anthocyanin-based, vitamin-based, and probiotic beverages. After being mixed with water, the active retention period is greatly shortened. With the increasing improvement of people's living standards, people are increasingly pursuing healthy bottled beverages. If a beverage bottle cap that can store solid ingredients and can be mixed as needed can be designed, before the user uses it, the nutritional ingredients and water are in a separated state, maintaining the activity of the raw materials and being mixed immediately when used. In this way, the manufacturer can avoid using preservatives, stabilizers, etc., and the user can also get a reassuring product. This design concept has been recognized by many people.

[0003] In the prior art, the bottle caps with built-in powder (contents) have deficiencies in use. The powder discharging operation is relatively cumbersome. It is necessary to perform operations such as pressing and puncturing after opening the bottle cap to achieve powder discharging, and powder discharging cannot be completed while opening the bottle cap. Therefore, it is necessary to optimize and improve its structure. Summary of the Utility Model
